Generate a WiFi QR code

Enter the network name, the password and the encryption type, and the WiFi QR code joins the network on scan - no typing, no dictating the password across a room. Android and iOS both support this natively in the camera app.

What is a WiFi QR code?

A WiFi QR code encodes the credentials of a wireless network in a short, standardised line:

WIFI:T:WPA;S:network name;P:password;;

Scanning it makes the phone offer to join that network. Nobody has to read a password off a laminated card, and a 20-character random password becomes as easy to share as a short one - which is the security argument for using this at all.

Where it earns its place

  • Cafés, bars and restaurants: on the table, on the menu, next to the till.
  • Holiday flats and hotels: in the welcome folder, where guests look first anyway.
  • Offices: a guest network code in reception, so visitors never touch the internal one.
  • At home: inside a kitchen cupboard door, for visitors and for the next router reset.

What to know before you print it

The password is stored in clear text inside the code. Anyone who can photograph the sticker has the password, exactly as if it were written out - so put a WiFi code where you would be willing to write the password, and use a separate guest network when that matters.

Pick the encryption that the router actually uses: WPA covers WPA, WPA2 and WPA3, WEP is only for old hardware, and no password is for open networks. Tick hidden network only if the SSID is really not broadcast, because the flag makes some phones search noticeably longer.

Frequently asked questions

How does a WiFi QR code work?
The code contains a line in the form WIFI:T:WPA;S:network name;P:password;; . A phone recognises that format and offers to join the network, so nobody has to type the password.
Does it work on iPhone and Android?
Yes. Both read WiFi codes directly in the camera app, iOS since version 11 and Android since version 10. Older Android phones may need a QR scanner app.
Is my WiFi password safe in the code?
The password is stored in clear text inside the code. Anyone who can photograph the code has the password, exactly as if it were written out - so treat a printed WiFi code like a written password and prefer a separate guest network.
Which encryption do I choose?
WPA covers WPA, WPA2 and WPA3, which is what almost every current router uses. WEP is only for old hardware, and "no password" is for genuinely open networks.
What does the hidden network option do?
It adds a flag telling the phone the network does not broadcast its name, so it searches for it explicitly. Only tick it when the SSID really is hidden, because it makes connecting noticeably slower.
